Custom cross-platform development services

Turn your idea into a scalable cross-platform application. We'll create for you software applications that are compatible with multiple operating systems, by allowing code sharing where a single codebase can be used across iOS, Android, and sometimes even desktop platforms like Windows and macOS. Our custom cross-platform development services also include integrating third-party services, APIs, and tools, such as payment gateways, social media platforms, analytics tools, and cloud services.

Kotlin Multiplatform

Kotlin Multiplatform, as a cross-platform framework, gained the ability to compete with cross-platform technologies that are far more established and older. Our Android developers are already familiar with Kotlin language and can seamlessly integrate Kotlin Multiplatform into your projects, maintaining native UI and functionality while sharing core logic across iOS and other platforms. This approach reduces development time and costs, since there is no need to hire both iOS and Android developers, when one developer can create mobile app for both platforms.

UI/UX design

Our designers create straightforward UX and visually attractive UI to increase conversion, engagement, and app adoption. Developers can use platform-specific native UI components and provide tailored functionalities for iOS and Android. By creating separate UI for each platform, users get that “native feeling", meaning they have intuitive and familiar behavior since some things work differently for iOS and Android.

why us?

Why should you consider outsourcing cross-platform developers?

If you've encountered a project that requires expanding your development team quickly, consider outsourcing. Instead of searching for additional freelance Android or iOS developers, which can be risky as you don't have a verified understanding of their expertise, choose a reputable mobile app development company. By outsourcing developers for cross-platform solutions, you reduce costs and get the app much faster. Cross-platform development companies have been operating for many years and wouldn't be successful if their developers weren't experienced and proven in creating scalable cross-platform applications.

Focus on other in-house activities

When you entrust an external cross-platform development team with part of the project, you have more time to focus on key business decisions. This way, you can be confident that the project will be delivered on time and that project management is at the highest level.

Entrusted developer expertise

You are sure you'll work with an experienced cross-platform developer who provides you with needed mobile solutions and delivers your mobile app within the deadline. Also, if your in-house developers are not familiar with the technologies that the project requires, outsourcing will solve this problem.

Quicker market entry

If you have a shortage of Android and iOS developers, you'll get your app to market faster by outsourcing additional resources instead of overwhelming your current developers with a larger workload for a longer period.

Keep up with industry trends

A trusted mobile app development company always keeps up with the latest trends and you'll get a high-quality code for your hybrid app. At the same time, it adheres to all rules and standards, ensuring you are secure, including from a security perspective as well.
